It's true, my sleep routine is unhealthy though. I used to play games alot on the computer and to a point that I forgot about the time. So sometimes, once I realized that I only had 2-3hrs of sleep and I went straight to bed to sleep. However, my brain was still active from all the actions in the games so even though i slept my mind still active and it started to wonder around. That's when I started to have dreams.

When I have a full sleep i can't dream.
